The woody legume, Albizia lebbeck, is native to tropical Asia, Africa and Northern Australia. Owing to its multi utility, it is widely planted as block plantation and in boundary across community lands. A field study was conducted by measuring biometric value of trees, viz., height, diameter at every 2 meters height using tree telescope. Besides biometric attributes, age was assessed in order to correlate the age-wise yield. The study was carried out in western agro-climatic zone of Tamil Nadu in different age classes of trees, viz., 1–5 years, 6–10 years, 11–15 years, 16–20 years, 21–25 years, 26–30 years and 31–35 years. The uniqueness of the present study is that, the yield model construction for Albizia was done for standard stem timber (Volume at diameter 20 cm overbark) and standard stem small wood (Volume between diameter limits of 20cm and 5cm both measured overbark). After computing the data and subjected for multiple linear regression analysis, the model was constructed, so as to develop yield table accurately for Albizia without the help of form factor. The study result developed two exclusive yield models namely standard stem timber yield model for Albizia was Y= (-1.212) + (-0.012* Age) + (6.506*Diameter) and standard stem small wood was Y= (-0.945) + (-0.045*Age) + (2.769*Diameter) + (0.262* No. of Branches). The prominence of the present study is that yield table computation for Albizia is possible accurately without destructive analysis and the cumbersome process of developing form factor.

Afforestation and reforestation have a greater potential for appropriate absorbtion of carbon from environment that helps in mitigating and reducing the global warming nature of both the developing and developed countries. Hence, the present study for assessing the carbon sequestration potential of 7 trees (Dalbergia latifolia, Albizia lebbeck, Dalbergia sissoo, Gmelina arborea, Swietenia macrophylla, Tectona grandis, and Terminalia bellirica) have been evaluated in Forest College and Research Institute (FC&RI), Mettupalayam in the surroundings of the Jakanari Reserve Forest, Northern part of Coimbatore for its biomass of trees, biomass carbon, ecophysiological (Photosynthesis and Transpiration rate) attributes and carbon isotope discrimination potential of trees. The study revealed that Dalbergia sissoo and Tectona grandis have the highest potential for biomass and biomass carbon production and as well as these two species also performed well under the eco-physiological condition by having the highest potential of growing in water scarcity conditions through carbon isotope discrimination identification. Dalbergia latifolia and Swietenia macrophylla are not able to cope with the prevailing dry condition; hence these species can be used for moist land conditions. Confirmation of the present study reveals that the Dalbergia sissoo and Tectona grandis are the best suitable tree species recommended for maximum carbon sequestration potential.
